ASTM A423 Seamless Carbon Alloy Steel Boiler Pipes

ASTM A423 Seamless Carbon Alloy Steel Boiler Pipes conforming to ASTM A423 standard are high-quality carbon alloy pipes for Boiler systems. As a professional Boiler Pipe, it combines the economy of Carbon Steel Pipe with the temperature resistance and corrosion resistance of Alloy Steel Pipe. Processed by seamless forming technology, it has excellent structural strength and adaptability to working conditions, and can stably meet the medium transmission requirements in scenarios such as industrial boilers and power station boilers.

For different Temperature sections of the boiler, this Pipe material performs outstandingly: In the core high-temperature heat exchange section, its carbon alloy material endows excellent high-temperature resistance performance and can be directly used as a High Temperature Steel Pipe, withstanding high-temperature steam impact; For the low-temperature water inlet or preheating section, it can be combined with Low Temperature Steel Pipe to avoid the risk of low-temperature brittle cracking and achieve full system temperature coverage. In addition, it features precise size control of Precision Steel Pipe, a smooth inner wall to reduce heat energy loss and fluid resistance, a tight interface to prevent leakage, and strictly complies with ASTM A423 standards, providing reliable pipeline support for the safe and efficient operation of the boiler system.

ASME SA213 T22 is a type of alloy steel pipe specified in the ASME SA213 standard.

The realevant detailed introductions and properties are as below:

1.Chemical Compostition(ASME SA213 Standard)

Carbon:0.05-0.15%,low-carbon design to reduce weld sensitization risk.

Cr(Chromium):1.9%-2.6%， enhances oxidation resistance and high-temperature srength.

Mo(Molybdenum):0.87%-1.13%, improves creep resistance and thermal fatigue resistance.

Mn(Manganese):0.3%-0.6%， enhance processabiliy(e.g.,cold forming.

Si(Silicon):≤0.5%,reduces oxide scale formation during service.

P/S(Phosphorus/Sulfur):P≤0.025%,S≤0.025%, strictly limited o improve material purity and reduce hot brittleness.

2.Merchanical properties(ASME SA213 Requirements)

Tensile Strength ≥415Mpa, ensures load-bearing capacity under high-temperature and high-pressure conditions.

Yield Strength ≥205Mpa, guarantees plastic deforamtion ability to avoid brittle fracture.

Elongation ≥30%, high ductility supports cold bending and forming processes.

Summary

ASME SA213 T22 is a classic material for high temperature and high pressure equipment below 550℃. With excellent anti-oxidation and anti-creep properties and mature processes, it is widely used in thermal power and petrochemical fields. Its core advantage lies in high quality control (such as UT/RT testing) and reliable high temperature stability in accordance with ASME standards, heat treatment specifications must be strictly followed to avoid failure. For ultra-high temperature or highly corrosive environments, upgraded materials (such as T91 or Super 304H) are required.
